Team Fortress 2

So I was playing in an Instant Respawn server run by NexusClan or whatever and the map being played was 2Fort. I decided to play Engineer and set my sentry and dispenser up at the top of my base's stairs (so it could have a clear line of sight towards anyone coming up the main entrance and the sewers).

Equipped with my Wrangler, I went to town on the enemy team. Taking out a bunch of scouts, pyros, a couple of demomen and a heavy. Then I see the server trying to start a votekick because I was "idling." Somehow the vote goes through despite me running around reparing the damage to both the sentry and the dispenser.

I really enjoy(ed?) playing on that server so I tried to get back in but I get a message telling me I'm banned from the server. And to make matters even worse, my brother (who was also playing the same game) tells me that the person who started the votekick says he made a mistake and kicked the wrong person. So what gives?

If that server has a website, try contacting the admin and explain the situation. But to tell you the truth, I blacklist servers where they kick or ban good players when it is not advertised as a noob only server.
